U.S. Playing Card Co.
The magician removes a prediction from a blue deck and lays it on a table face-down. The spectator selects a card from a red deck and lays it face-down. The magician shows the red deck to the audience, they are all the same card - the volunteer had no choice! However, when the volunteer's card is turned over, it is different than the rest of the deck! Has the magician failed? No, he turns over his card and it matches the spectator's selection! A comedy routine this is a fouler. If you can spread cards, you can do this trick.
